WATCH: Will Smith Proves He Can Still Rap 'Fresh Prince Of Bel Air', With Gary Barlow On Keyboard... (VIDEO)

Will Smith has come a long way since he first hit the public scene as the Fresh Prince.

But this weekend, the star of Men in Black 3, in cinemas this week, proved he hasn't forgotten a word of the rap that first brought him to public consciousness in his sitcom The Fresh Prince of Bel Air.

The hit TV show finished in 1996 after six years but, sitting on Graham Norton's sofa at the weekend, Smith seemed completely happy to join in with the live audience - every single one of whom knew every single word to his Fresh Prince of rap - and like them, he was word-perfect.

And Gary Barlow was able to join in too, with a keyboard delivering the familiar twangs that accompanied the rap during the opening credits of every episode. The tune was composed by uber-producer Quincy Jones.

The show starred Will Smith as an exaggerated version of himself, a teenager from West Philadelphia sent to live with his wealthy relatives in their huge Bel Air mansion, with the inevitable clashes. The series was shown in the UK on BBC2.
